No more, no more, please. We’re already taking off our shoes, getting our junk scanned, waiting in line, dangling our goo in plastic bags, and basically suffering through ludicrous post hoc measures that do nothing to improve our security. And now the TSA is dispatching ‘behavioral experts’ to watch you as you stand in line. Don’t look nervous, don’t act annoyed, don’t do anything that these arbitrary arbiters of the appropriate might notice!
